RANGE WATER-BACK. a'

SPECIFICATION forming part' of Letters Patent No. 227,334, dated May 4,1880l i Application filed August 8, 1879.

To all 'whom it may concern Bc it known that 1, JAMES G. WELDON, ofPittsburg, in the county of Allegheny and State of Pennsylvania, haveinvented a certain new and useful Improvement in Range Water-Backs; andI do hereby declare the following to be a full, clear, and exact description of the invention,l such as will enable others skilled in the art towhich it pertains to make and use it, reference being had to theaccompanying drawings, which form part o this specitcation, in which-Figure l is a view ofthe old-style waterback. Fig. 2 are twoperspectives of my improvement from opposite points of view. Fig. 3 is avert-ical longitudinal section. Fig. 4 is a plan section, a; x, of Fig.3. Fig. 5 is a view showing position of water-back in vrange and itsadaptability to right or left feed.

This invention relates to the construction of waterbacks for stoves andranges; and it consists in making the water-back L-shaped and cuttingthe holes for the water-pipes transversely through the lateral branchthus formed, whereby the circulating-pipes can be readily attached. Thewater-back is reversible and applicable to various positions, and theheating-surface is increased.

It further consists in a partition following the L shape, whereby agreater vertical height is acquired for the action of the heat toproduce circulating currents.

ln the drawings, A designates the main portion of my water-back, havingthe lateral extension B, giving the whole an L shape, the part Boccupying an erect position when the water-back is in place.

I cut the holes a a transversely through both walls and thread them.Holes'a are for the attachment of the cold-water pipe, and holes a! forthe hot-'water pipe, and the addition of the part B gives to the columnsformed by the partition G a greater vertical height for the formation ofcirculating currents.

The invention is applied as follows It is set in the {ire-pot to formeither of its sides or back of the fire-pot, and in either of the threelocations it is reversible end for end. Thus the water-back is capableof being placed in six different ways, and in all the pipes may pass,without joints or elbows, in a straight line from the water-back throughthe iue. The pipes being fitted to but two of the holes, the remainingtwo are closed with screwplugs.

The double set of holes gives me theadvantage of being able to reversethe position ofthe water-back at will. Thus the same waterback, bychanging the plugs and position, serves for the various locationsrequired for the trade, and dispenses with the necessity otl having alot of differently-shaped patterns.

I am aware that an integral extension to a water-back is not broadly new5 but my invention relates to the construction of the waterback with aview to convenience in applying it to ranges and adapting it to thevariable conditions of kitchen-walls, direction of setting, and positionof the range-boiler.

I therefore claim as my inventionl. A reversible water-back having annpward extension with the openings et a' on opposite sides thereof,substantially as set forth.

2. The water-back A, having the extension B, lateral openings a a', andI -shaped partition C, substantially as set forth.

In testimony that IV claim the foregoing I have hereunto set my handthis 12th day of June, 1879.

JAMES G. WELDON.
